Vitamin E for wry neck. B complex for many other neurological issues.I seem to recall @Royal Chick saying B12 and Vit E.
Found this online:
“
Wry neck can be a symptom of a Vitamin B1 (thiamine) deficiency.
Chicks can be more prone to a Vitamin B1 deficiency if they are fed medicated chick feed for too long. The coccidiostat Amprolium in medicated chick feed can inhibit the absorption and utilization of Vitamin B1.
Chicks can also be more prone to dietary deficiencies if their parents’ diet was deficient in vitamins as well”

Or so I gathered when I was researching it.
